As a grandparent you are always looking to please an active grandchild . They not only were active at GSE they had fun. They even offered extras because we were repeat customers. I would recommend them wholeheartedly for a family fun day.

The bumper boats are a must do for my family when we visit the Cape. The batting cage is a bonus for my husband to participate in. Harwichport has so much family friendly activities to offer for the whole family.

What a fun place to take our grandchildren with things that we could do together- bumper boats, zip line, batting cages, arcade games - and not break the bank. Staff and facilities get an A+ ! !

Bumper Boats is a great, quick, fun way to get wet on a hot afternoon and shoot people with water you don't know. Everyone has a blast here.
